WEATHER-STRI P.

SPECIFICATION forming part of Letters Patent No. 330,866, dated November 24, 1885.

Application filed September 3, 1885. Serial No. 176,114. (No model.)

To all whom it may concern:

Be it known that I, J oHN Y. BASSELL, of Leesburg, Loudoun county,Virginia, have in vented certain new and useful Improvements in XVeathcr-Strips; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

My invention relates to that class of weatherstrips in which a strip of rubber or other fieXible material is combined withastrip of metal, which serves to hold the rubber, and constitutes the part to which the attaching nails or screws are driven; and it consists in a certain novel adaptation of the said rubber to the metal, whereby economy in material is effected, and a more perfect and secure union of said parts is accomplished.

I will first describe my invention atlength, and will then point out in the clauses of the claim at the end of this specification what I deem to be its essentially novel feature.

Referring to the accompanying drawings, Figure 1 represents aperspective view of a section of weather-strip constructed in accordance with my invention Fig. 2 represents a crosssc :ctional view of the same. Fig. 3 is a perspective view of aportion of the rubber strip as it appears before its application to the metal strip. Figs. 4 and 5 are views of modifications.

Similar letters of reference in the several figures indicate the same parts.

The letter A indicates the rubber portion of the device, and B the metal part thereof. By preference I take a strip of rubber of the desired dimensions and fold it partially back on itself, as shown in Fig. 3, so as to formalooped or tubular portion, a, and asingle ply or thickness, a, from the point a to the point a I then unite the overlapped portion to the body ofthe strip by means ofa line ofstitching, 8, applied as shown in Fig. 3; or, in lieu of the stitching, I employ suitable rubber cement or other competent cement or glue for effecting the firm union of the parts. Having thus prepared the rubber,I connect to it, by means of suitable machinery adapted to the purpose, the metal strip B in such manner as that onewing or flange,b,of the metal will be overlapped and turned under the single thickness a of the rubber, while the other flange, 2), thereof will be made to embrace both plies ct (L as well as the third ply,c,of the rubber, as clearly shown in Fig. 2. The ply a, itwill be observed, terminates at the point aiwhile the ply a continues beyond the said point, and is doubled back on itself so as to form the third ply, a. This shortening of the ply a would not be practicable were it not for the fact of its firm connection with the ply a by means of the stitching or otherwise, since without this connection it would pull out of the metal in handling before the application of the material to use. The saving gained in thus shortening the rubber ply a amounts in the narrowest size of weather-stripping to at least one seventh or eighth of the whole quantity employed,while in wider sizes the proportion saved is still greater, owing to the fact that in such sizes the relative width of the metal increases, and consequently the amount of rubber turned over within the metal is also increased. WVhile I prefer to shorten the ply a and lap the ply a around it, so as to form the third ply, a, the same saving of material may be effected by shortening the ply a and turning over the extended ply a, as shown in Fig. 4. After the rubber and metal have been connected as described,holes t, for the passage of the attaching-nails, are made by striking a punch (or a series of punches at a time) down through the metal strip, near its middle, as shown in Figs. 1 and 5. The forcing of the punch through the metal causes an inwardlyprojecting burr, j, to be produced, which extends through both of the upper superposed thicknesses or plies, a and a of the rubber, as shown in Fig. 5, and serves as an efficient means for preliminarily holding the ply (i within the metal, and dispenses with the necessity of using stitches or cement for the purpose. Of course in the application of the strip the nails will pass down through the apertures thus formed, and will furtherfirmly secure the rubher to the metal. For additional strength, however, I prefer to positively connect the two plies of rubber together by stitching or otherwise before the metal is connected.

I am aware that weather-strips have been made composed of a strip of rubber doubled, i and both the ends clamped by a metal plate, as shown in Patent No. 92,613, granted 0. A. Judd, July 13, 1869; but such aconstructiou is inferior to mine, because not only is the metal. strip with its double fold of rubber inside too bulky, but an unnecessarily large amount of the rubber or fabric is used,which is wasted, performing no function whatever.

Having thus described my invention, what I claim as new is 1. In a weather-strip such as described, the combination of the flexible strip' formed into a loop, as shown, by being overlapped on itself, and having a single thickness or ply, a, left projecting beyond the top,with the metal strip having one wing turned in to embrace the extremity of the single ply or thickness a, and

the other wing turned in to embrace all three I plies, a a and a,whereby a saving of flexible strip is effected, substantially as described.

2. In a weather-strip such as described, the combination of theflexible strip formed into a loop, as shown, and having the plies constituting the loop sewed or otherwise positively secured together, with the metal strip having one wing turned in to embrace the extremity of the single ply or thickness or, and the other wing turned in to embrace and hold all three plies,a a and a, substantially as and for the purpose set forth. 7
